How to upgrade a GAC'ed dll

Hi all

I'm building an application that contains a dll that will be used by several
other applications.
The dll is installed in the GAC, to make it easy for everyone to find it.
When my application is upgraded, I'm also installing a policy in the GAC so
any call to the old dll is redirected to the new one.


My problem is the following scenario;


1) My.dll 1.0.0.0 is installed in the GAC

2) My.dll is upgraded to 1.1.0.0 (replaces the previous version in the GAC)
policy.1.0.My.dll is installed in the GAC, redirecting 1.0.0.0 to 1.1.0.0

3) My.dll is upgraded to 1.2.0.0 (replaces the previous version in the GAC)
policy.1.1.My.dll is installed in the GAC, redirecting 1.1.0.0 to 1.2.0.0



After step 3, when an application is trying to use My.dll version 1.0.0.0,
it only gets redirected to My.dll version 1.1.0.0 and not to 1.2.0.0 which I
wanted.


Isn't it possible to use version redirection multiple steps?
Do I need to add a new policy AND update my old policys everytime I upgrade
the dll?

Thanks!

Hello Fredrik,

Did u provide the publisher policy with your new assemblies? http://msdn2.microsoft.com/en-us/library/7wd6ex19(vs.71).aspx

Hi Michael

Yes, (at least) one publisher policy is included with the assembly.
I'm creating a msi using WiX, which installs my application, registers the
dll in the GAC and finally registers the publisher policy in the GAC.

What bugs me is that it seems that I need to include one policy-dll for each
major.minor-version that has been released earlier, when I'm creating a new
msi.

Hello Fredrik,

Yep, it is.
when u publish the new version it's better to provide the new published policy
for this
or update existed with the new redirection
